10 Most dangerous Sea Creatures in the World

+1 vote
52 views

Covering 70% of the world’s surface the sea is home to some of the most unusual, mysterious and deadly animals on the planet. As someone who has spent plenty of time bobbing around on the surface of the sea my mind has often drifted to what lurks below. Fortunately the statistics provide some comfort and it is apparently quite rare to be eaten alive whilst frolicking in the ocean. However, I expect that’s what all those people who did get eaten were thinking, and lets face it, it’s a pretty unpleasant way to go.

Let's take a look at 10 most dangerous Sea Creatures in the World:

1. Box Jellyfish

Box Jellyfish is the most dangerous sea creature in the world. The most dangerous creature in the ocean doesn’t have a venomous bite, rows of sharp teeth, or even an obvious mouth for that matter. But nevertheless, the box jellyfish, also known as the sea wasp, is more responsible for human deaths on the continent of Australia than snakes, sharks, and saltwater crocodiles put together.

2. Crocodiles

Always keep yourself alert around saltwater river, because they strike when it’s least expected. Saltwater crocodiles are reported to have a bite force 10 times greater than that of great white shark, and unlike great white sharks it can walk on land (that’s terrifying). Like most crocodiles, saltwater crocodiles are not fastidious in their choice of food, and select their prey according to availability. However, claims in the past have suggested that saltwater crocodiles are responsible for thousands of humans fatalities annually, most of which remain unreported.

3. Blue Ringed Octopus

Another small creature that packs a big venomous punch is the Blue Ringed Octopus. Growing no more than 8 inches in length, this cephalopod feeds on small crabs and shrimp, yet still has enough venom to kill a human. In fact, they have enough venom to kill nearly 30 humans within a matter of minutes. To put it another way, its venom is 10,000 times more powerful than cyanide.

4. Stonefish

This small breed of fish has an unusual look as it resembles a rock, which is very useful hide from predators living around. Unfortunately those who accidentally step upon the fish, will be greeted with sharp spines that can easily penetrate bare feet. Most stonefish stings occur as a result of stepping on them, while it’s less common to sting when picked up. Stonefish sting can occur also on beach, not only in water, because they are able to stay out of water for 24 hours. When someone get sting, victim feel pain due to wound, but also get a small dose of neurotoxin which can shut down their respiratory system and even cause heart to fail. Venomous, dangerous and fetal to humans.

5. Great White Shark

This predator is no stranger to the list of dangerous animals and is almost constantly and incorrectly perceived as the world’s most dangerous animal. The nature of the Great White is often misunderstood, the Great White is not out on a mission to attack every human being that steps foot in the water. The Great White tends to attack humans when they are hunting for food, it’s nothing more than basic instinct.

6. Tiger Shark

Also known as sea tiger, this large shark has reputation of having widest food spectrum of all sharks, consuming variety of prey ranging from fish, seals, birds, squids, turtles to dolphins and even smaller sharks. The bull shark is quite imposing, but the tiger shark is something else. They don’t seek out humans as food, but they often visit shallow reefs, harbors and canals creating potential encounter with humans. It is extremely rare for sharks to bite humans, but tiger sharks are responsible for a large percentage of fetal shark attacks, making them one of most dangerous animal living under oceans.

7. Stingrays

Stingrays are one of the more passive creatures in oceans and hardly ever attack. The majority of stingray incidents happen when divers and swimmers accidentally step on them, causing the stingray to defend itself using it’s sting. While majority of stingray ‘attacks’ are not serious, there are some stingray species which can be fatal. Better watch your step when you dive.

8. Sea Snakes

If you ever thought that the land snakes are only deadly threat to humans, then you may want to think again, sea snakes also posses a venom that’s extremely dangerous for humans. But it’s extremely rare for them to inject its toxin while biting the prey, if they do however, aftereffects can be horrible as hell. When they bite, they only inject a small amount of venom, but victim doesn’t experience its effects instantly. Within an hour symptoms start to occur that include headache, a thick feeling tongue and vomiting., which is later followed by elapid attack and a progressive paralysis of muscles.

9. Lionfish

Lionfishes are found in the Caribbean and Eastern Atlantic. They are part of the ‘Scorpionfish’ family. Probably they are one of the most beautiful sea creatures in the oceans. But better don’t get close to them. While a sting from a lionfish is not deadly these fish can provide a very painful attack with some powerful venom.

10. Fire Coral

You can look, but do not touch! They are the reason why scuba divers use gloves. Fairly closely related to jellyfish and anemones these small organisms can deliver a power sting with it’s invisible tentacles. The results can vary from a mild irritation to severe pains and is sometimes even associated with nausea and vomiting.

Dinosaurs roamed the Earth over 200 million years ago and were the dominant terrestrial vertebrate for 135 million years. It is believed their extinction came about because of changes in the climate they couldn’t adapt to. Birds are the closest relative to a dinosaur that we have.

Let's take a look at 10 most interesting information about Dinosaurs:

1. Dinosaurs walked the earth for over 165 million years. They lived during a period of time known as the Mesozoic Era, or Age of Reptiles.

2. At the end of the Cretaceous Period they became extinct – that was around 65 million years ago. During this time there was a great deal of volcanic activity and many earthquakes.

3. Many people believe that dinosaurs became extinct because an asteroid hit the earth changing the climate dramatically. It is believed that dinosaurs couldn’t adapt to these changes.

4. The word dinosaur means terrifying lizard. This name was invented by Sir Richard Owen in 1842.

5. The oldest known dinosaur is Eoraptor, a meat-eater that lived 228 million years ago.

6. The vast majority of dinosaurs were plant eaters. Fierce carnivores like Tyrannosaurus Rex and Giganotosaurus get all the press, but it's a fact of nature that the meat-eating "apex predators" of any given ecosystem are tiny in number compared to the plant-eating animals on which they feed.

7. It's true, some plant-eating dinosaurs (like Stegosaurus) had brains so tiny compared to the rest of their bodies that they must have been only a little bit smarter than giant ferns. But meat-eating dinosaurs large and small, ranging from Troodon to T. Rex, possessed more respectable amounts of grey matter compared to their body size, since they required better-than-average sight, smell, agility and coordination to reliably hunt down prey.

8. Dinosaurs are classified as reptiles. They are divided into two groups based on the structure of the hip. One group has lizard-like hips and the other group has bird-like hips. Most dinosaurs hatch from eggs, and they could not fly or live in water.

9. The biggest dinosaurs were over 100 feet long and 50 feet tall, the Sauropod was the largest dinosaur. The smallest dinosaurs were the size of a chicken and were called Mussaurus.

10. The color of all dinosaurs is unknown because no one was alive at that time in history. There are currently over 330 described dinosaur species and this number is growing.

About 1.3 million people die in traffic accidents every year. The World Health Organization has declared 2011-2021, "A decade of action for road safety." But while many of those deaths could be prevented by better driving, there are some roads that test the skill, and courage, of any driver.

Let's take a look at top 12 deadly roads in the World you would never want to drive on:

1. North Yungas Road, Bolivia

Also known as the “Road of Death” in the Yungas region of Bolivia. It is legendary for its extreme danger and the Inter-American Development Bank christened it as the “world’s most dangerous road”. One estimate is that 200 to 300 travellers are killed yearly along the road. The road includes cross markings on many of the spots where vehicles have fallen. It is a regular occurrence for buses and trucks to go tumbling to the valley below, especially when they try passing each other.

2. Jalalabad–Kabul Road, Afghanistan

Many roads have been dubbed "most dangerous," but the 65-kilometer stretch of highway from Jalalabad to Kabul has more claim than most, snaking through Taliban territory. But it's not the threat of insurgency that makes Highway 1 so dangerous -- it's a combination of the narrow, winding lanes that climb up to 600 meters through the Kabul gorge and the reckless Afghan drivers trying to overtake the heavily-burdened haulage trucks.

3. James Dalton Highway, Alaska

The Dalton Highway is a 667 km road in Alaska. It begins at the Elliott Highway, north of Fairbanks, and ends at Deadhorse near the Arctic Ocean and the Prudhoe Bay oil fields. Although appearing serene at first glance, is filled with potholes, small flying rocks carried by fast winds, and worst of all it runs through the middle of nowhere.

4. Karakoram Highway, Pakistan

The Karakoram highway links China and Pakistan at the Khunjerab Pass, at an altitude of 4,693 meters. It's prone to landslides and floods and to make matters worse, the road is unpaved in Pakistan. But it is still a tourist attraction, passing through some spectacular gorges along the old Silk Road. It has been named the "Friendship Highway" by the governments who built it, despite 810 Pakistani and 82 Chinese workers losing their lives during construction, mostly in landslides.

5. Guoliang Tunnel Road, China

The Guoliang Tunnel is carved along the side of and through a mountain in China. It may be hard to see in the photo, this road was hollowed out of the side of a mountain by several villagers from the town of Guoliang. Before the construction of this mountain pass the village was cut of from the rest of civilization by the surrounding cliffs. Although it doesn’t see much traffic, due to its construction it is inherently fairly dangerous.

6. The Zoji Pass, India

The Zoji La is a mountain road between Kashmir and Ladakh and it looks like little more than a dusty pathway through the western Himalayas. But it's a lifeline that keeps the people of Ladakh in touch with the rest of the world, although it's often cut off by heavy snow in winter. The nine-kilometer stretch of road meanders over the mountain at 3,528 meters, with no barrier on one side and just the hard rock face on the other. Definitely not for anyone suffering from vertigo or a fear of landslides.

7. Skippers Canyon Road, New Zealand

The Skippers Canyon Road, located in New Zealand, is unbelievably scary as it’s made from a very narrow cut in the middle of a sheer cliff face. This winding road actually requires a special permit to drive. If you do manage to get permission though, be ready for a slippery challenge and good luck if you run into someone coming from the other direction.

8. Los Caracoles Pass, Chile

These steep, dizzying bends slalom through the Andes between Uspallata in Argentina and Los Andes in Chile. The remote location, its elevation of 3,176 meters and the procession of articulated lorries make the drive even more frightening. There's no safety barrier either. Nonetheless, even tourist coaches use the road, at least when it's not cut off by snow in winter. An easier option is to go by air or take the Transandine Railway -- if it's ever brought back into service.

9. The Stelvio Pass, Italy

The Stelvio Pass located in Italy, at 9045 feet is the highest paved mountain pass in the Eastern Alps, and the second highest in the Alps, slightly below the Col de l’Iseran 9088 feet. Some roads look a lot more dangerous than they really are. With more hairpins than Helena Bonham Carter, the Stelvio Pass looks like a child’s scribble over the hills. The road climbs almost two kilometers and, with just a low concrete barrier between you and the steep mountain drop, it’s best not to look down. A bit too much speed on one of the road’s 60 180-degree corners could spell disaster.

10. The Widow-maker, United Kingdom

This scenic country road through England's Peak District was named by the Road Safety Foundation in 2010 as the United Kingdom's most dangerous road, with 34 fatal or serious accidents from 2006 to 2008. Many of the casualties are motorcyclists, who come to enjoy the wide open space and bucolic scenes. However, the road's treacherous bends, edged by steep embankments and stone walls, make it far more dangerous than it looks, leading to its grim local nickname, the "widow-maker."

11. Sichuan-Tibet Highway, China

The Sichuan-Tibet Highway, a high-elevation road between Chengdu and Tibet where landslides and rock avalanches are common, is undoubtedly part of the problem. It is a road with a record of over 7,500 deaths for every 100,000 drivers has reason to be feared. Due to rock slides, avalanches, and poor weather drivers should certainly use caution.

12. The coast roads, Croatia

In a country that experiences an average of 11,650 traffic accidents a year, it's no wonder that Croatia also makes it onto the Association for Safe International Road Travel's list of some of the world's most dangerous roads. Congestion and speeding are a problem along the Adriatic coastal roads, which are infamous in the region for their blind corners, sharp bends that cling to the cliff face as well as a frequent lack of safety barriers.
